Gas Hookup & Information
A. Fuel
Before making gas connections, ensure the
appliance being installed is compatible with the
available gas type.
B. Gas Pressure
Proper input pressures are required for optimum
performance. Gas line sizing requirements need to
be made following.
NFPA54
C. Gas Connection
Before making gas connections, ensure the
appliance being installed is compatible with the
available gas type.
B. Gas Pressure
Note: Have the gas supply installed in accordance with
local building codes, if any. If not, follow ANSI 223.1.
Installation should be done by a qualified installer
approved and/or licensed as required by locality. (in the
Common weath of Massachusetts installation must be
performed by a licensed plumber or gas fitter).
Note: A listed (and Common wealth of Massachusetts
approved) 3/8 in. T-handle manual shut-off valve and
flexible gas connector are connected to the 3/8 in.
Control valve inlet. If substituting for these components,
please consult local codes for compliance.
•
Incoming gas line should be piped to the 3/8 inch
connection on the manual shutoff valve.
WARNING
Fire Risk
Explosion Risk
Verify inlet pressures.
• High pressure may cause over fire condition.
• Low pressures may cause explosion
• Verify minimum pressures when other
household gas appliances are operating.
Install regulator upstream of valve if line
pressure is greater than
½
psi.
Pressure requirements for appliance are shown in table
below.
Minimum pressures must be met when other household
gas appliances are operating.
WARNING
Fire Risk
Explosion Risk.
• Gas build-up during line purge may ignite.
• Purge should be performed by qualified
technician.
• Ensure adequate ventilation.
• Ensure there are no ignition sources such as
sparks or open flames.
A small amount of air will be in the gas supply
line. When first lighting appliance it will take a
short time for air to purge from lines.
Subsequent lighting of the unit will not require
such purging. Never allow the ON / OFF valve
to remain in the open position without pressing
and continuing to hold igniter button FIRST.
WARNING
CHECK FOR GAS LEAKS
Fire Risk
Explosion Risk
Asphyxiation Risk.
• Check all fittings and connections.
• Do not use open flame,
• After the gas line installation is complete, all
connections must be tightened and checked
for leaks with a commercially available
leak-check solution. Be sure to rinse off all leak
check solution. Be sure to rinse off all leak
check solution following testing.
Fittings and connections may have loosened
during shipping and handling..
